Roadworks 490 x 290

Latest update

Upcoming works


  1. Road works will begin in early February, after the installation of water mains along a 1.5km stretch of the road in early January.
  2. ATCO Gas contractors will undertake gas main relocation works in the Abernethy Rd reserve from Soldier Rd to the Byford Tavern carpark. These works will consist of construction of a new gas main by horizontal direct drilling and the removal of the existing gas main. The works will commence early - mid February and are expected to be completed by mid March 2019.
  3. Our electrical contractor Anser Group will undertake electrical power undergrounding works on Abernethy Rd, from Gordin Wy to South Western Hwy. These works will consist of installation of underground power cable in preparation for the removal of the existing overhead powerline. The works will commence on 21 January 2019, and it is expected that they will be completed by mid March 2019. It is anticipated that Western Power will remove the existing overhead powerline and power poles in mid-April 2019.

Traffic control will be in place during the works from 7am to 5pm and residents are asked to take extra care when entering and exiting Abernethy Rd.


Weather conditions and operational changes may require these works to be rescheduled at short notice. Residents are encouraged to check this page or contact the Project Manager, Trevor Markey on 9420 2968 for more information.


We thank you for your continued patience as we work on this critical project for our community.

Project summary

  • The Shire of Serpentine Jarrahdale is the fastest growing locality in Western Australia and rapid growth in population brings an increase in road traffic.
  • The local area of Byford fronting Abernethy Road is fast growing and with that, the capacity of Abernethy Road is rapidly approaching the limit for safe operation and will exceed that in the very near future.
  • Some members of our community have expressed concern with the current capacity and traffic safety of Abernethy Road and expressed a desire for it to be upgraded.

Anticipated future traffic volumes

  • By 2030: 10,800 to 16,800 vehicles per day will use Abernethy Road (in 2012 it was just under 2,849).

The current road won't cope

  • There is enough room in the current roadway (generally 28 metres wide) to fit 4 lanes (2 in each direction) plus turning lanes and a central median as well as footpath either side and street trees from around the Byford Secondary College extending towards the east.
  • Widening will be needed

Benefits the upgrade will bring

  • Reduce congestion.
  • Safer opportunities for turning (both at roundabouts and into/out of your driveways)
  • Safer opportunities for cycling and walking with shared footpaths and street lighting
  • Minimise accidents: Reported crash data shows there has been 69 crashes on Abernethy Rd between Kardan Boulevard and the South Western Highway (Jan 2012 – Dec 2016)
    • The majority were vehicles entering/leaving driveways or turning right at an intersection
    • The second higher were vehicles from 'one direction' e.g. rear end/side swipe type crashes
    • 82% property damages only
    • 12% required medical attention, and
    • 6% resulted in people being hospitalised, 0 fatalities

State Government expectations for Abernethy Road

  • Set out in Perth and Peel @ 3.5 million strategic documents Abernethy Road will transition from being a ‘local road’ into what is known as a ‘regional road’.

Current status

  • We are working with state agencies to relocate essential services like telecommunications, water, power etc.

Construction stages

Stage 1 - current

  • Site setup and clearing of vegetation

Stage 2 - current

  • The Shire is working closely with the following agencies to relocate essential services:
    • Telstra
    • NBN Co
    • ATCO Gas
    • Western Power
    • Water Corporation
    • Public Transport Authority

Stage 3

  • Upgrade of Beenyup Brook culvert crossing

The unexpected delays that have been experienced during the relocation of services have allowed the Shire to undertake a review of the existing plans for the creek crossing works. A new approach has been developed that will avoid the need for the prolonged road closure that has previously been communicated. It is now expected that any closures will be limited to short term closures and wherever possible will be undertaken outside of business hours to avoid inconveniencing surrounding schools and businesses. Information regarding any closures will be made available via our Facebook page and Roadworks website.

Stage 4

  • Road upgrade works within the rail reserve

These works require changes to rail signalling systems which are under the control of the Public Transport Authority. During this stage a complete closure of the crossing for a period of approximately 3 days will be required. The Shire is working closely with the Public Transport Authority to ensure that this happens at a time that will minimise disruption to surrounding schools and businesses. Information regarding any closures will be made available via our Facebook page and Roadworks website.

Stage 5

  • Earthworks, drainage and pavement works
  • Stage 5 will commence as soon as possible after the completion of Stage 2
